2 Claims.

This invention relates to a device for forming curls in strands of hairby what is known as permanent waving. The present'invention is animprovement on the hair waving device illustrated,

" described and claimed in United States Patent No. 1,974,625 issuedSeptember 25, 1934 jointly to John C. Murray and myself.

An object of the present invention is to provide a hair waving devicewhich may be more readily manufactured and assembled, and which iscomposed of fewer parts than the device shown in said Patent No.1,974,625.

Another object of the invention is to provide in a hair waving device ofthis character integral means forming the hair clamping means and themeans for insulating the device from the scalp of the person beingtreated.

Further and additional objects and advantages not hereinbefore referredto will appear herein- 0 after during a detailed description of thedevice which is illustrated in the accompanying drawing wherein:

Fig. 1 is a perspective view of the device on an enlarged scale. I

Fig. 2 is a sectional view thereof taken substantially on line 2-2 ofFig. 1 looking in the direction of the arrows.

Fig. 3 is a detail perspective view of the integral clamping andinsulating pad, and

Fig. 4 is a detail perspective view of the metal connecting clip usedwith said insulating and clamping pad.

In view of the fact that the construction of the device shown herein isidentical with that shown in said Patent No. 1,974,625, with theexception of the integral insulating and clamping member, it is believedthat only a brief description of the corresponding details of structureneed be set forth herein.

The device constitutes what is known as a heater and is constructed tobe used with steam as the heating agent, although it should beunderstood that the device might also employ electrical or chemicalheating means. The heater constitutes a chamber, which chamber is formedof two half sections I0 and I l, preferably made of suitable sheetmetal, each section being substantially U-shaped in cross-section. Thesections are pivotally connected together adjacent one of their ends,wherefore they may be swung to open position to allow the strands ofhair to be clamped upon a rod I2 which is rotatably carried by theheater and upon which the hair is wound. The hair sections I0 and II areclosed upon the rod I2 when heat is to be applied to hair wound (Cl.132-3G) upon the rod and said sections are clamped and locked in closedposition by means of spaced links I3 pivotally connected to the section9 I at the end opposiite to the pivotal connection between the sectionsand adapted to receive therebetween a tongue I4 carried by the sectionIll. A locking cam or eccentric i5 is pivotally mounted between thelinks I3 at the free ends thereof, and when said cam or eccentric isturned into engagement with the tongue M by the handle 56 the two halfsections of the heater or chamber are fully closed and locked in thatrelationship. The section II intermediate the ends of the heater andadjacent the bottom edge is provided with an opening in which is mounteda swiveled fitting I! for receiving and connecting to the heater a steaminlet conduit I8, as clearly shown in Figs. 1 and 2. The tongue I4carried by the section I!) is the extended end of a plate I9 secured tothe outer side of the section Ii). A similar plate 20 is secured to theouter side of the section II and has an extended end to which the linksI3 are pivotally connected. The opposite ends of the plates I9 and 2!]are similarly extended beyond the sections and have pivotally connectedthereto spaced links, not shown herein, which form the hinged connectionbetween the half sections and to one of which the rod I2 is rotatablyconnected. Channels 2| are secured to the outer sides of the plates I9and 2!! which channels have the ends of their arms turned inwardly ofthe channel, as shown at 22, for a purpose later to be explained. Thesubstantially Z-shaped metal members 23 are secured to the sections itand II, it being noted that the long arms of the members 23 extendwithin the sections In) and H and are secured to the side walls thereof.The members 23 embrace the plates is and 26, while their outer portionsconstitute channels 2311, the bases of which bear against the adjacentsides of the separate channels 2i which are secured to plates I9 and 2t)and to the members 23 by suitable rivets or other securing means. Thedescription of the heater thus far set forth is identical with theconstruction of the heater shown in the said Patent No. 1,974,625.

In accordance with the present invention the inner arms of the channels23a of the Z-shaped members 23 are-provided with a plurality of openingsZ i, in the present instance there being three of these openings, andsaid openings constitute part of the securing means for the combinedhair clamping and insulating member. This member, indicated in itsentirety by the numeral 25, is an integral rubber pad having on one sideand at one edge thereof an upstanding rib 23 provided on each of itssides with undercut, longitudinally extending grooves 27. Spaced fromthe rib 26 and extending parallel thereto intermediate the longitudinaledges of the pad is a second upstanding rib 28 which has secured theretoa metal channel 29, the ends of the arms of which are bent inward- 1y,as indicated at 29a, so as to clamp the channel in position upon the rib28. The channel 29 is provided with a plurality of spaced outstandingknobs or projections 30, there being three of these projections in thepresent illustration, inasmuch as there are three of the openings 24 inthe channel 23a.

In assembling the combined clamping and insulating members upon theheater the inturned ends 22 of the channels 2| are slipped into theundercut grooves 2'. adjacent one end of the rib 26, and then themembers are slid longitudinally into position on the heater, whichaction brings the ribs 26 into the channels 2! When the membars havebeen thus positioned with the ribs 28 in the channels 2! they are thenbent around to position the channels 29 and the ribs 28 within thechannels 23a and such positioning of the channels 29 causes the knobs orprojections 30 carried thereby to snap into the openings 24 in thechannels 23a, wherefore the channels 29 with their cooperating ribs 28are securely locked in position in the channels 23a. It will be seen duetothe manner in which the rib 26 is secured in the channels El and theribs 23 and associated channels 29 in the channels 23a, that thecombined clamping and insulating members are securely attached to theheater and in a manner allowing for great ease of assembly.

It will be understood that the portions of the members which lieadjacent to the ribs 28 when the members are mounted on the heater,constitute the hair clamping portion of the members,

While those portions of the members lying outwardly of the channels 2|and 23a are the insulating portions thereof and are adapted to belocated adjacent to the scalp of the person being treated when theheater is being used.

Although a preferred embodiment of the invention has been illustratedand described herein it should be understood that the invention issusceptible of various modifications and adaptations within the scope ofthe appended claims.

Having thus described my invention I claim:

1. In a hair waving device of the character described and including aheater formed of two pivotally connected sections each of which hasconnected to one of the sides thereof a pair of channels with thechannels of each pair disposed so as to face at right angles to eachother, and combined insulating and hair clamping members secured to saiddevice and comprising integral rubber pads each having on one sidethereof a pair of spaced parallel ribs, one of which extends into one ofthe channels of said pair and the other of which extends into the otherof the channels of said pair, and means for locking said ribs in saidchannels.

2. In a hair waving device of the character described and including aheater formed of two sections each of which is provided with means forsupporting a hair clamping member and means for sup-porting aninsulating member, in combination with combined insulating and hairclamping members secured to said device and each comprising integralrubber pads having a clamping portion and an insulating portion, saidportions and both of said means having cooperating elements providing aninterlock therebetween acting to maintain the combined insulating andhair clamping members in position.
